Research Groups / Bio-process Membrane Group

We are developing a novel membrane separation technology, that allows substance separation as never has been possible before, through the combination of efficient biomass-derived saccharide components and fermented substances.

Research is being carried on the following subjects related with Bio-refinery and membrane:

Research Topics

Condensation of Saccarides used In Fermented Microorganisms

Condensation of Saccharides Used in Microbial Fermentation

Physical pretreatment and enzyme based saccharization treatment are needed for biomass used in microbial fermentation where, generally, high-concetrated Saccharides are needed but, it is clear that biomass-derived enzymic saccharification liquid has a low concentration of glucose and its diversity of subproducts act as inhibitors of Microbial fermentation. We develop and evaluate techniques to perform at the same time saccharide condensation and removal of subproducts by applying biomass-derived enzymatic hydrolyzates.
Selected Separation of Fermented Metabolites From Cultures of Post-fermented Microorganisms

Selective Separation of Fermented Metabolites from Post-Microbial Fermentation Culture Solutions

Selective separation (Condensation) of objective metabolites coming from fermented liquid obtained post-microbial fermentation is an extremely important technique if material settlement is economically considered. As an example of this: in order to implement the usage of Bio-ethanol, combustible obtained by alcoholic fermentation of yeast (ethanol) at a lower cost while its demand rises, several technological developments are required.
Material Surface Functionalization through Simple Application of Syntethic Polymer

Material Surface Functionalization through Simple Coating with Syntethic Polymer

We are developing a novel technique to control discretionally the physical properties of surfaces (physical, chemical characteristics). here, concretely, we aim to control the physical properties of a surface through "painting" it with an special polymer syntethized by us. From here, it is possible to produce (applicable in separation - analysis) molecular detection surfaces, uncontaminated surfaces and surfaces with catalytic functionalities.
Development of Novel Surface-Acting Agents with Separation Functionality

Development of Novel Surface-Acting Agents with Separation Functionality

Surface acting agents already have a familiar presence in detergents but we aim to develop surface acting agents with new functionalities different than "cleaning". For example, Surface acting agents with separation functionalities. We are developing DNA surface acting agents with the ability to separate DNA depending on its base arrangements, also, Surface acting agents with the capacity of separating different types of fat particles through its insertion into separation membranes.
